Correct. We may also want to add some support for mgr:mem page and stuff, but that's extra bonus. > tcmalloc > jemalloc > ptmalloc3 > nedmalloc > ptmalloc2 > malloc > * tcmalloc seems to be faster for smaller sized allocations but > otherwise on par with jemalloc. > > Some others I could not find easy benchmarks on: > gnumalloc > dlmalloc > phkmalloc > c c? All of the above (both groups) provide malloc type interface, which means they drop right in. Just need to be a little careful with our use of mallinfo. From what I know we only use malloc, calloc, free and mallinfo. any plugins or third-party libraries also need the same concern if we use a malloc implementation not fully providing the same functions as the system malloc.
